[PROBLEMS] To provide a water / oil repellent excellent in processing stability of water / oil repellent processing without using a fluorine-containing monomer, particularly a fluoroalkyl group-containing monomer. (A) a non-fluorine polymer having repeating units derived from a non-fluorine (meth) acrylate ester monomer, (B) a wax having a melting point of 52-88 ° C., (C) an aqueous medium, and ( D) A water / oil repellent which is an aqueous dispersion comprising an emulsifier, wherein the non-fluorine (meth) acrylate ester monomer is represented by the formula: CH2 = CA11-C (= O) -O-A12, wherein , A11 is a hydrogen atom or a methyl group, and A12 is a linear or branched hydrocarbon group having 18 to 30 carbon atoms. The water- and oil-repellent agent wherein the emulsifier comprises a sorbitan ester and another emulsifier, and the hydrophilic-lipophilic balance (HLB) of the emulsifier is 7.5 to 13.5.
